Abstract: 488,739. Making stranded conductors. BRITISH INSULATED CABLES, Ltd., and PACKER, J. L. March 24,1937, No. 8653. [Classes 83 (ii) and 83 (iv)] [Also in Group XXV] Rolling, drawing.-A stranding head of short axial length for inserting in existing non- compressing stranding machines so as to make stranded conductor comprises a preliminary shaping die 19 closely followed by a pair of rolls 20 and then by a drawing die 3. The sectional shaping die, Fig. 2, imparts the desired cross-section to the conductor as it is being formed, the rolls 20, driven or undriven, consolidate the strander conductor, increase the area of contact of the individual strands and reduce the interstices, while the drawing die 3 draws down the conductor and reduces still further the size of the interstices. Preferably, the shape of the apertures in the die 3 is such as to exert a maximum compression on those portions of the conductor where the roll pressing was a minimum. The conductor is drawn through a capstan assisted by the rolls 20 when driven. Gearing 24, 25 slowly rotates the stranding head. The die 19 is secured in a split die holder 15 by a taper bore nut. Both die 19 and 3 are rifled. The framing comprises a rotatable carrier 4, as described in Specification 434,506, fixed to hollow trunnions 8, 9 with ball bearing 10 and ball thrust bearing 12. The die 3 is rotatably adjusted so that its rifling suits the pre-spiral lay of the conductor. The dies and rolls may be shaped, Figs. 5, 6, and 7 (not shown), to make circular section compressed stranded conductors. The roll pass may be adjusted, e.g. as described in Specification 432,309 and may be mounted and driven as described in Specification 354,927, [Group XXV]. The apparatus may also be used for non-prespiral strand of non-circular section by preventing rotation of the head. When the preliminary die is sized to act also as a drawing die, a drip lubricant from a reservoir 30 is supplied to the work.

Abstract: 127,113. Gestetner, D. May 30, 1918. Stencils and stencilling.-A process of copying documents &c. consists in the employment of a stencil formed upon a porous support of Yoshino or like paper or textile fabric by the action of light en asphalt. The stencil may be produced in various ways. In one method, a sheet of sized paper is coated with asphalt and exposed to light. The coating is then transferred to a temporary support and the image developed by means of benzene or other solvent, and the coating is then transferred to the Yoshino paper &c. In another method, the Yoshino paper is coated or impregnated with the asphalt, which is afterwards exposed and developed: The copies may be obtained by passing an inked roller over the stencil, or by securing the stencil to a support between which and the stencil is a layer of ink and bringing the surface to be printed into contact with the stencil. By employing suitable inks, such as quick-drying varnish inks, copies may be obtained resembling prints produced by the use of engraved plates. Copies resembling half-tone prints may be produced by employing, in the preparation of the stencil, positives produced from half-tone negatives.

Abstract: 287,578. Westinghouse Electric & Manufacturing Co., (Assignees of Skellett, A. M.). March 25, 1927, [Covention date]. Vacuum tubes.-A relay comprises a gas ionization device 2 connected to the control electrode of a multiple-electrode discharge device 14, preferably of the kind described in Specification 280,870. The device 2 preferably has three electrodes 3, 4, 5 in neon or argon at a pressure of 1000 microns, the electrodes 3, 5 being connected to the tuned input circuit 6, 7. The electrode 4, which is arranged at a distance from the electrode 3 less than the mean free path of the gas molecule, is connected to the control member 17 of the device 14, the large cathode 15 and small anode 16 of which are in circuit with a source of alternating current 24 and a relay 22 effecting the desired control. Normally the control member 17 is negatively charged and blocks the anode circuit, but currents of the frequency of circuit 6, 7 establish a potential sufficient to ionize the gas in device 2, which then permits the charge on the control member 17 to leak away, thereby energizing the relay 22.

Abstract: 1,146,122. Valves. ENGLISH ELECTRIC CO. Ltd. 21 Feb., 1968 [24 Feb., 1967], No. 9063/67. Heading F2V. [Also in Division G1] An actuator for a valve (not shown) comprises a sealed housing 9 filled with wax 13 and including a piston 11 extending into the housing, an electrical conductor 14 disposed in the wax for heating and expanding the wax so as to displace the piston 11, and circuit means (not shown) coupled to a control arm 30 for controlling the electrical energy supplied to the conductor 14 in dependence on the displacement of the piston 11. The conductor 14 is wound on ceramic support 16 and a coiled stainless steel capillary tube 17 is also disposed in the housing, compressed air being forced through the tube 17 for cooling purposes. The piston 11 acts on a plate 26 and thus on a sleeve 21A, 21B coupled to a shaft 24 of the valve against the action of a spring 27 coiled round the sleeve. Belleville washers 25 are interposed between the plate 26 and plug 22 of the sleeve 21A, 21B to prevent overloading of the shaft 24 and an overload switch 31 is provided to cut off the supply to the conductor 14 on compression of the washers 25. In use the conductor 14 is fed with a current which is the sum of a standing current, sufficient to bring the actuator to its working temperature and a control current derived from a control signal dependent on the rate of flow required through the valve controlled by the shaft 24. This control current is progressively reduced by movement of the control arm 30 on the sleeve 21A as the piston 11 is displaced to minimize overshoot and hunting. When the control signal is removed, the circuit means is arranged to cut off the standing current whilst the actuator cools, and this cooling can be accelerated by the passage of compressed air through the tube 17. Additional external cooling of the housing 9 may also be employed to further reduce time lag on the return stroke of the piston 11.

Abstract: Organochlorosilanes containing at least one impurity which reacts with free Cl2 or free Br2 at a faster rate than will the organochlorosilane, e.g. labile hydrogen, are purified by contacting them with free Cl2 and/or Br2 under anhydrous conditions for a period sufficient for reaction between substantially all the impurity and the halogen.  Silanes suitably have the formula RnSiCl4- n or R2ClSi(RSiCl)xSiRCl2, where R is a mono or polyvalent hydrocarbon, perfluoroalkylethyl, cyanoalkylethyl or haloaryl radical, n is 1, 2 or 3, and x is 0 or an integer. The reaction may be conducted in an inert organic solvent, e.g. benzene, toluene, CHCl3, CCl4 or C2H3Cl3, between 10-70 DEG  C., using 0.0001-0.1 mol. of halogen per mole of Si. The purified product may be hydrolysed to a polysiloxane; e.g. purified dichlorodimethylsilane is hydrolysed to yield a polydimethyl siloxane, and subsequently endblocked with trimethylsiloxy groups by treatment with hexamethyldisiloxane in the presence of sulphuric acid.
